SOLE-LAYING MACHINE.

Specification of Letters Patent.

Patented Feb. 4,1908.

Application filed A ril 19. 1906- SerialNb.312|558- To all whom it mayconcern:

Be it known that I, JOHN J. Hers, a citizen of the United States,residing at Lynn, in the county of Essex and Commonwealth ofMassachusetts, have invented an Improvement in Sole-Laying Machines, ofwhich the following description, in connection with the accompanyingdrawings, is a specification, like letters on the drawings representinglike parts.

This invention relates to sole laying or leveling machines of the ty ewherein the sole is acted upon by a form s aped to correspond with thedesired shape to be given to t e whole or any part of the shoe sole.Machines of this kind as ordinarily constructed, are known as directpressure machines.

Prior to my inventionthe most common construction has been to mountthese forms rigidly in the machines; that is, incapable of. any rollingor adjusting motion, such as would permit the same to conform or adaptthemselves to the level, pitch or inclination of the last upon which thesole is mounted. Since there is much inequality in lasts, particularlywhen of wood, as well as in the uild of the shoe, it is rarely the casethat a sole is evenly presented to the form that is to act upon it.Consequently, either the shoe or the last or both, are subjected tounequal damaging pressure, or else the work is shifted, distorted, orotherwise disarranged in the effort to adapt itself to the immovable orrigidly mounted form. My invention comprises an improved means formovably and preferably universally mounting the form for free adaptationor conformation to the sole presented to it, so as to give to the solethe required contour or shape without undue or improper inequality ofpressure or tendency to shift the work or damage the last.

My invention also contemplates accessory devices for use in connectionwith the above, all of which will be best understood from a descriptionof the best embodiment of my inventionthat I have as yet put into useand which is shown in the accompanying drawings, wherein,-

Figure 1 is a side elevation of the machine containing such embodiment;Fig. 2, a front view thereof; i-z :5. 3, a detail of a part of themachine hen-.1 in which the form is mounted; Fig. 4, a vertical sectionon the dotted line 4-4, Fig. 3; Fig. 5, a view similar to Fig. 3, butviewed from the opposite side; Fig. 6, an under side or plan view ofFigs. 3 to 5, inclusive, the form being omitted.

in the particular embodiment of my invention selected for illustrationherein and shown in the drawings, referring first to Figs. 1 and 2, themachine therein shown is substantially the same as that illustrated inmy U. S. Patent No. 581,662, dated April 27, 1897, to which referencemay be had, like reference letters representing like parts. Since theconstruction of such machine is well known in the art, it is unnecessaryto give in detail the construction or mode of operation thereof otherthan to call attenniachine comprising the two last supporting tableswhich are caused to move inward and outward and to rise and fallalternately to present their respective shoes thereon to forms 9depending from the headC at the top of the mach ne. In said Patent No.581 ,662 the forms 9 are rigidly or inimovably held in and by said head,except that they are supported by springs m, which permit them to givesomew shoe rises from beneath. Referring to Figs. 3 to (3 of theaccompanying drawings, the corresponding form g, is, in accordance withmy invention, mounted in such a manner that it may adapt itself tothesole and last presented to it. The head C, as in said patent, isprovided with a housing for the spring 1n, the latter at its upper endbeing seated against a plate n on the end of an adjusting wheel, 0, bymeans of which the abutment plate n ma be adjusted to vary the tensionof the spring. At its lower end (see Fig. 4) said spring is seated upona head or form carrier 1, fast upon the end of a rod 2, that risesthrough said spring and adjusting nut and at its upper end has clam edupon it the stop nut 3. In the bottom ace of this form carrier 1, is asemi-spherical recess for acomplementary shaped boss 4, on the formsupporting plate 5. This plate 5 has a vertical central aperture for theheaded supporting device 6, that is screwed into the bottom of said rod2, the opening in the said plate above the said supporting device beinglarger than the said device to iat as the last supported 70 tron to thefact that the machine is a twin 1 said form may be slid into and outfrom support at 7*,

position under and secured to the said plate. he form is positioned andthere-held by a locking device 7, pivotally connected to said andadapted to swing down over and to cooperate with an adjusting screw 8 onthe form, which adjusting screw is'of a length accurately to fit betweenthe hooked end of. said locking device and the hub thereof, whereby saidform is held against movement in either forward or I backward direction,yet is adjustable withconforming.

out interfering with its retention as described, by turning said screwin its support on said form.

When a last with a lasted shoe thereon with a sole. positioned orpreliminarily laid is brought up to the form in the operation of the.machine, the moment the sole or a part thereof engages the formthelatter responds to the approaching sole and the last beneath it andwithout substantial resistance, positions or adapts itself to theapproaching last. Thus, if the. last is onesided or its spindle hole isout of alinement,

in an irregular or abnormal position to the form, the latter willconform thereto, in stead of requiring the sole and "its last to-do theconforming and this conformation of the form takes place without anysacrifice of effective pressure, and without any shifting actionimparted to the sole; for obviously, the shape of the form will beimparted to the sole, or the pressure will at all points of the solebe-more properly imparted thereto, as well when the form is conforming,as when it is rigid. In fact, a more accurate and uniform pressure ispossible'w'ith a conforming form, such as here described, than would bepossible were it rigid with no possibility of the sole surfaceconforming to it; which is practically the case where the entire shoe,ast, jack or form and its. carrier must be lift are compensated for bycompression of the spring m, as in the earlier type of machine, theconforming action of the form being additional to this vertical yieldingaction.

It will be noticed that the center of the universal connection which,.in the embodiment shown in the drawings, is at or about or if for anyother reason the sole is presented- Of course, all variations 'in tocause equal the 'point marked 9, is so close to, in fact being shown assubstantially coincident with, the deepest part of the adjacent formsurface, that the rolling or conforming action of the form does not tendto give any appreciable bodily creeping sidewise or longitudinalmovement of the form with reference to the sole, so that there-is notendency to displace the sole on. the shoe, nor the shoe on its last. Itis desirable with a conforming form of this type that means be providedfor centering it always in normal position after each effective action;otherwise the form might be displaced considerably at one. action oroperation, and if left there, would be presented improperly to the nextshoe to be operated upon.

For the purpose-of returning the form always to normal position whenfreed from pressure, I have provided the carrier 1, with a plurality,preferably four recesses, for the re storing pins 10, each rounded atits lower end by preference and adapted to press upon the top of. theform carrying plate 5. These pins are headed at their upper ends toprevent them from dropping out at any time and upon their headed endsare seated springs 11, which at their upper ends are in.

turn seated upon a ring-like plate .12, secured.

.upon the top of said head 1. "these springsbeing of substantially equaltension actnor. mally to center or balance the plate 5 and its form innormal or central position so far as its levelis concerned, althoughsaid pins are perfectly free to yield singly or together, as

may be necessary to bring the form into posi. tion lJOCOIlfOIIIl to theapproach ing last and sole thereon. The form g is also free to ina-horizontal plane to adapt itself to the alinement of the lastpresented to it and restore the alinement to normal after each%peration, l have provided the (see igs. 4 and 5) at its end oppr device7 with a projecting e stands between the depen said head 1 and. havingrected ends segmen oppc.

' l5 tens ards each other two arms. A spring depending arms norn. andtowards the opp center the latter betwe Obviously, any deflection ofsaid to one side or the other due to any adjustment of the aline; meritof the form to that of an approaching last will cause one of said armsto be swung away from its normal. po tion, causing thereby equal andopposite mover ent of the mating arm. As soon the said form is freed thespring 1. 5 will draw the two arms together,

thereby centering the ear between them and restoring the form to itsnormal position.

My invention 18 particularb ml in connection with either sole laying orleveling s to draw said upon wood lasts, which vary greatly in size,vice 0, together with the centering and reshape and in the alinement ofthe spindle holes, although it has other advantages that will beapparent to those skilled in the art.
